Need help identifying missing components on GTX 1080 FE

Hi, I was directed to this forum by nvidia support as they were unable to help me out, hopefully there’s an engineer here with access to a schematic or board view!

A friend of mine was replacing the thermal paste on his GTX 1080 Founders Edition, and slipped with a screwdriver when re-fitting the cooler, breaking a small transistor and a capacitor from the board, and now the card won’t work. Unfortunately these tiny components have been lost.

I have experience repairing motherboards and soldering delicate electronics so my friend has offered to send me the card to repair and keep, to replace my aging GTX 780, but I’m unable to identify the parts that I’ll need to replace, Q501 and C503 in this photo. They are on the back of the board near the power connectors.

Q501 is labelled “LP” in this photo of a working 1080 FE, I could guesstimate the value of the ceramic cap, but I’m at a loss when it comes to this transistor.

Any assistance would be greatly appreciated.

Thanks, Alex
